Axiom’s ticket price for India’s astronaut on Ax-4 mission: $59 million

10:38 am

According to reports today in the India press, the price Axiom charged India’s space agency ISRO for training and then flying its astronaut on the just completed Ax-4 two-week mission to ISS was $59 million.

The expenditure by ISRO includes cost of [Shubhanshu] Shukla’s training for the mission as well as that of a seat on SpaceX’s Dragon spacecraft for the 20-day trip that launched Shukla, and three others — Peggy Whitson from the US, Slawosz Uznanski-Wisniewski of Poland and Tibor Kapu of Hungary — to space.

Earlier reports had suggested Axiom was charging $70 million per ticket. If the $59 million is accurate and applies to the charges Poland and Hungary paid, then Axiom’s revenue for the flight was $177 million. From that it would have to pay SpaceX (for the launch and the use of its Grace capsule) and NASA (for the use of ISS). Based on past history, SpaceX likely charged around $70 million for the launch. The cost for using Grace is unknown. NASA’s fees for a two-week visit to ISS were probably around $10 million plus.

My guess, based on this very limited information, is that Axiom made some profit from the flight, ranging from $20 to $50 million.

Scientists: The Sun’s bright corona acts to impede coronal mass ejections

10:23 am

Using data gathered by the Solar and Heliospheric Observatory (SOHO) since its launch in 1995, scientists have determined that when the Sun’s corona (its atmosphere) is bright, it acts to slow and even block the ejection of coronal mass ejections (CMEs), which if they impact the Earth’s magnetic field can have a harmful effect on our modern technology.

Using data from NRL’s Large Angle and Spectrometric Coronagraph Experiment (LASCO) on board the joint European Space Agency (ESA)-NASA Solar and Heliospheric Observatory (SOHO), the NRL team [National Research Laboratory] compiled nearly three decades of observations of the solar corona. They studied the extensive dataset to investigate trends in the brightness of the Sun’s corona and compare them to CME velocities over the same period. Their study found a strong correlation between the two datasets, with bright regions of the solar corona appearing to relate to substantially slower CME velocities and, in some cases, perhaps entirely precluding CMEs.

This data will help solar weather observers better predict the arrival of CMEs, should they erupt from the Sun aimed at Earth. It will also allow them to gauge the risk of CMEs even occurring.

SpaceX planning to use Starship for manufacturing in space

10:00 am

It appears the enthusiastic investment response last week to the potential of using Varda’s re-turnable capsule for manufacturing in space (especially of pharmceuticals) has caught SpaceX’s interest. According to a news report yesterday, SpaceX has now begun developing a program to use Starship for the same purpose, delivering the raw materials in orbit for short or long periods while these products are produced automatically and then returning them for sale on Earth.

Under the plan, internally called Starfall, SpaceX’s Starship rocket would bring products such as pharmaceutical components to space in small, uncrewed capsules, said one of the people, who spoke on condition of anonymity because the matter is confidential.

Starship would then deploy the capsules, which would spend time in orbit before reentering the atmosphere, where they could be recovered back on Earth, the person added.

This description by this anonymous source seems inaccurate however. Why even consider using these small separate capsules when the entire operation can be put inside Starship, which can then bring everything home when ready? Moreover, Starship’s ability to put a lot of mass in a large space up into orbit gives it an great advantage over the smaller capsules being developed by companies like Varda.

Either way, the advantages of weightlessness for producing products for profit are finally being realized, after decades of blockage by government intransigence. Since the Challenger accident in 1986 and Reagan’s order that the shuttle would no longer not be used for commercial purposes, NASA has forbidden production on its spacecraft and ISS of any products for sale afterward.

Now that the cost of launch has dropped significantly (Thank you Elon Musk!), many investors and companies are seeing great potential for manufacturing in space. And those profits will help feed a private space industry, making the government agency of NASA even more irrelevant.

SpaceX completes its first launch for Amazon

11:39 pm

SpaceX tonight successfully launched 24 Kuiper satellites for Amazon’s internet constellation, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its first launch, landing on a drone ship in the Atlantic. This was the third new stage launched in 2025, and follows the company’s recent pattern of launching between one to three new stages per year. The two fairings completed their 27th and 28th flights respectively. As of posting the satellites had not yet been deployed.

This was SpaceX’s first launch for Amazon, out of an initial contract of three launches. The launch was also Amazon’s third Kuiper satellite launch, the previous two by ULA on its Atlas-5 rocket, launching 27 satellites each. While ULA seems poised to begin regular launches for Amazon, having a contract for 46 launches (with completed two), the contracts for Blue Origin’s New Glenn (27 launches, and ArianeGroup’s Ariane-6 (18 launches) are more uncertain. Neither company has achieved any launches on their contracts, and it is not clear when either company, especially Blue Origin, will ever begin regular launches.

This slow launch pace from these companies is a serious problem for Amazon, which is required by its FCC licence to get 1,600 satellites in orbit by July 2026. For this reason, there are rumors that Amazon might switching more launches to SpaceX, as it has the capability of to launch frequently.

We will have to wait and see.

The leaders in the 2025 launch race:

88 SpaceX
37 China
10 Rocket Lab
8 Russia

SpaceX now leads the rest of the world in successful launches, 88 to 64.

7:18 pm

SpaceX this evening successfully placed another 26 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its fourth flight, landing on a drone ship in the Pacific.

The leaders in the 2025 launch race:

87 SpaceX
37 China
10 Rocket Lab
8 Russia

SpaceX now leads the rest of the world in successful launches, 87 to 64.

SpaceX also has another launch scheduled in just a few hours from Cape Canaveral, launching 24 Kuiper satellites for Amazon. This is SpaceX’s first launch for Amazon, out of contract of three launches. It will also be the third Kuiper satellite launch, the previous two by ULA on its Atlas-5 rocket, launching 27 satellites each.

First good image released of interstellar object 3I/Atlas as it plunges through the solar system

3:25 pm

First good image of instellator object 3I/Atlas
Click for original image of 3I/Atlas.

Astronomers using the Gemini North Telescope in Hawaii have obtained the first good image of the interstellar object 3I/Atlas, as it plunges within the orbit of Jupiter on its way through the solar system.

That picture is to the right, cropped to post here and overlaid on top of a map showing the interstellar object’s calculated path through the solar system.

The picture clearly shows this is a comet, with central nucleus surrounded by a cloud of dust and gas. The data also suggests its nucleus has a diameter of about twelve miles. That it resembles a comet also suggests it is a dirty snowball, made up of ice and rocky material mixed together.

Because it will never get closer to the Sun then just inside the orbit of Mars, it is not likely it will ever get bright enough for naked eye observations. At the same time, it is large enough and will be close enough to make possible some excellent observations as it zips by and leaves the solar system sometime in the fall. The previous two identified interstellar objects, Oumuamua and Comet 21/Borisov, were either too small or too far away as they flew past to get this kind of good data.

Another win for a blacklisted professor

2:59 pm

Professor Timothy Jackson
Music historian Timothy Jackson

Fight! Fight! Fight! After the public University of North Texas (UNT) blacklisted and dismissed professor Timothy Jackson in 2020 from his job as editor of the music history journal he founded for daring to express some academic conclusions the faculty and students didn’t like, he sued.

After a five year battle, Jackson and the university have now settled out of court, with the terms of the settlement [pdf] largely a big win for Jackson.

First the background: In 2019 woke music theorist Philip Ewell of Hunter College in New York gave a presentation to the Society of Music Theory where he claimed 20th century music theorist Heinrich Schenker was a “virulent racist” whose “racist views infected his music theoretical arguments.”

Jackson, who had devoted his career studying Schenker and had co-founded at the university the Journal of Schenkerian Studies focused expressly on Schenker’s works, knew this was patently untrue. For example, Schenker was also a Jew who was a victim of German anti-Semitism and lost many relatives in the Holocaust, facts that Ewell somehow did not think important to mention. To counter Ewell’s historical slanders, Jackson decided to dedicate the next issue of the journal to this issue, presenting essays from both sides. He even asked Ewell to write an essay.

Ewell did not respond. In Jackson’s own essay he outlined in detail the historical facts — as he knew them as an expert on this subject — that put the lie to Ewell’s claims. As Jackson noted, “Ewell peddled a ‘conspiracy theory’ that is ‘part and parcel of the much broader current of Black anti-semitism.'”

Instead of celebrating this perfect example of free speech, the university immediately moved to punish Jackson.

The failed MethaneSat climate satellite apparently had problems from launch

10:24 am

According to a detailed New Zealand news report today, the failed MethaneSat climate satellite — funded and operated by the Environmental Defense Fund — apparently had significant problems during its short fifteen month life-span, going into safe mode many times, before failing completely last month.

An earlier report from this same news outlet described more fully the issues — which began in September 2024 only about six months after launch.

The mission’s chief scientist has now said more intense solar activity because of a peak in the sun’s magnetic cycle has been causing MethaneSAT to go into safe mode. The satellite has to be carefully restarted every time.

There has also been a problem with one of the satellite’s three thrusters, which maintain its altitude and steer the spacecraft. MethaneSAT says it can operate fully on two thrusters.

It appears there is a lot of unhappiness in New Zealand for spending $32 million on this project that was designed, built, and operated by an environmental activist organization with little space experience.

What is clear now is that the spacecraft likely got relatively little data during its fifteen month life span.

Webb spots aftermath of collision of two galaxies

10:06 am

colliding galaxies
Click for source.

Using the Webb Space Telescope, astronomers have discovered the collision of two spiral galaxies that appears to have caused a supermassive black hole to collapse in its wake.

The Webb false-color infrared image to the right shows the two galaxies as the red dots, both surrounded by a ring, with the supermassive black hole the bluish spot in between but offset somewhat to the left. Follow-up radio observations suggested that this bluish spot was a supermassive black hole, having a mass of a million suns and sucking up matter from the giant gas cloud that surrounds it.

The team proposes that the black hole formed there via the direct collapse of a gas cloud – a process that may explain some of the incredibly massive black holes Webb has found in the early universe.

This hypothesis however has enormous uncertainties, and requires a lot more observations to confirm. The black hole could simply exist unrelated to the galaxy collision, having come there from elsewhere. Or it could be from a third galaxy in this group that these initial observations have not yet detected.

The image however is quite cool.

House follows Senate in canceling most of Trump’s proposed NASA budget cuts

9:45 am

Like pigs at the trough
Like pigs at the trough

The House appropriations committee’s draft budget for NASA has followed the Senate appropriations committee in canceling all of Trump’s proposed NASA budget cuts, though it has shifted that funding significantly from science to manned space operations.

The House Appropriations Committee released the draft text of their version of the FY2026 Commerce-Justice-Science bill that funds NASA today. Like their Senate counterpart, the House committee would essentially keep NASA at its current funding level instead of imposing the severe 24.3 percent budget cut proposed by the Trump Administration. The CJS bill also includes almost $2 million for a White House National Space Council even though the Trump Administration has yet to establish one.

Unlike the Senate, which mostly kept the budget the same across all NASA departments, this House draft budget would reduce science and aeronautics spending from about $8.2 billion to $6.8 billion. Trump had requested only $4.5 billion for these departments.

In turn, the House would increase Trump’s request for NASA’s manned operations from $10.8 billion to $11.9 billion. Note that Trump’s proposed budget had already called for an increase here, so the House is clearly shifting funding to manned space in an enthusiastic manner.

At the same time, the House continues funding for the SLS and Orion programs Trump wishes to cancel. Both of these projects are over budget and behind schedule. Neither is very useful in the long run for exploring the solar system. If the House truly wanted to save money, it could easily fund all the cuts in science by cutting the billions spent yearly on these pork projects, and still lower NASA’s budget in total.

Based on the draft budget’s language [pdf], it is unclear whether the House has also funded the Lunar Gateway space station, as the Senate has, another useless pork project that Trump wishes to cancel.

I should note that the appropriations committee’s overall draft budget [pdf] does reduce the federal budget by about 2.8 percent. This is a marked change from past budgets, which often claimed (a lie) to cut spending but really only reduced the rate of budget growth. It appears the House is finally making some effort to shrink the size of the budget, though that effort is quite wimpy.
